By default, jConnect for JDBC sends plain text passwords over the network to Adaptive Server for authentication. However, jConnect also supports symmetrical and asymmetrical password encryption and can encrypt passwords before they are sent over the network. The symmetrical encryption mechanism uses the same key to encrypt and decrypt the password whereas an asymmetrical encryption mechanism uses one key (the public key) to encrypt the password and another key (the private key) to decrypt the password. Because the private key is not shared across the network, asymmetrical encryption is considered more secure than symmetrical encryption. When password encryption is enabled, and the server supports asymmetric encryption, this format is used instead of symmetric encryption.
To use the asymmetric password encryption feature, you must
have a server that supports password encryption, such as Adaptive
Server 15.0.2.
